摘要：
1.图书管理系统后端接口1.后端接口1.1books/models中的设置表。图书管理系统的副本来自django。dbimportmodelsclassBooks（models.Model）：btitle=模型。CharField（max_length=20）bpub_date=models.DateField（）bread=models.IntegerField（）bcomment=models.Integer
1.1 books/models.py 中设置表
from django.db import models class Books(models.Model): btitle = models.CharField(max_length= 20 ) bpub_date = models.DateField() bread = models.IntegerField() bcomment = models.IntegerField() is_delete = models.BooleanField(default=False)
1.2 urls.py 中设置路由
from django.urls import path
from books.views import * urlpatterns = [ path('book/', BooksView.as_view()), ]
1.3 book/views.py 视图函数
from django.http import JsonResponse
class BooksView(View): def get(self, request): books = Books.objects.filter(is_delete=False) book_list = books.values('id','btitle','bpub_date','bread','bcomment') book_list = list(book_list) data = { "code": 0 , "msg": "success", "books": book_list } return JsonResponse(data) def post(self, request): body_json = request.body.decode() body_dict = json.loads(body_json) btitle = body_dict.get('btitle') bpub_date = body_dict.get('bpub_date') bread = body_dict.get('bread') bcomment = body_dict.get('bcomment') book = Books(btitle=btitle, bpub_date=bpub_date, bread=bread, bcomment=bcomment) book.save() return JsonResponse({"code": 0 , "msg": "success"}) def put(self, request): body_json = request.body.decode() body_dict = json.loads(body_json) id = body_dict.get('id') btitle = body_dict.get('btitle') bpub_date = body_dict.get('bpub_date') bread = body_dict.get('bread') bcomment = body_dict.get('bcomment') book = Books.objects.get(id=id) book.btitle = btitle book.bpub_date = bpub_date book.bread = bread book.bcomment = bcomment book.save() return JsonResponse({"code": 0, "msg": "success"}) def delete(self, request): body_json = request.body.decode() body_dict = json.loads(body_json) id = body_dict.get('id') book = Books.objects.get(id=id) book.is_delete = True book.save() return JsonResponse({"code": 0, "msg": "success"})
2.1 测试获取所有图书接口
http://127.0.0.1:8000/book/
返回结果
2.2 测试创建图书接口
http://127.0.0.1:8000/book/
.postman测试提交数据
{
"btitle":"红楼梦",
"bpub_date":"2018-02-04",
"bread": 100 ,
"bcomment": 0
}
结果
2.3 测试修改图书接口
http://127.0.0.1:8000/books/
postman测试提交数据
{
"id":5,
"btitle":"红楼梦",
"bpub_date":"2018-02-04",
"bread":100,
"bcomment":0
}
结果
2.4 测试删除数据接口
http://127.0.0.1:8000/books/ postman测试提交数据 { "id":15 }
结果
